Description
Technical field
This utility model relates to the purifier of a kind of low-concentration organic exhaust gas or foul smell, relates in particular to photocatalysis deodorization purifier.
Background technology
Along with the expansion of worker, Agricultural Development and urban population, the pollution problem of foul gas is outstanding day by day, caused to people's quality of life to have a strong impact on, and the health of the direct harmful to human of meeting.Aspect foul smell source, city, the collection of municipal wastewater and processing procedure are to cause the main cause of foul smell discharging, and wherein the foul smell emission behaviour of sewage pumping station and sewage treatment plant is the most serious.In addition, also can discharge a large amount of foul gass in places such as the collection of domestic waste, feces, transhipments, to around environmental quality do great damage, also affect the image of modern metropolitan cities simultaneously.Along with the raising of the public, in rapid increase, become and one of environmental issue to be solved at the incident of the complaint of malodorous pollution problem and complaint to living environment quality consciousness.
Conventional foul gas improvement technology mainly contains absorption method, absorption process and biological decomposition method etc.But because the particularity of municipal wastewater foul smell that system discharges, said method is difficult to it is carried out economy, effectively handles, and is badly in need of exploiting economy and effectively administers new technique.
In recent years, be that the photocatalysis oxidation technique of catalyst receives publicity in the waste gas purification Application for Field with the metal oxide semiconductor.This technology is directly utilized ultraviolet light activated catalyst at normal temperatures, makes its surface generate free electron (e) and hole (H
+) right, the luminous energy that absorbs is changed into chemical energy, promptly have photocatalysis.When being free G﹠W steam to exist, free electron on the catalyst surface or hole are decomposed and can be produced the hydroxyl radical free radical (OH) of strong oxidizing property, oxygen (O), ozone (O3) and the hydrogen peroxide (H of atomic state with adsorbed water or steam effect
2O
2) etc., these materials have very strong Oxidation, thereby with the smell substance in the waste gas (as hydrogen sulfide, ammonia etc.) oxidation Decomposition, reach deodorizing effect.
Titanium dioxide (TiO2) is the photocatalyst that using value is arranged most at present, and existing application in the waste gas purification field.Yet, simple can only utilize the ultraviolet light of wavelength during as photocatalyst less than 387.5nm with titanium dioxide, the light bigger for wavelength can't utilize.Because the natural light medium wavelength is less than the light proportion very little (＜4%) of 387.5nm, therefore general photocatalyst can't effectively utilize natural light.And because light wavelength that most ultraviolet source produces also distributes in certain limit, its medium wavelength also can't be utilized effectively greater than the light of 387.5nm, causes energy dissipation to a great extent.In these cases,, make photocatalyst can utilize the light source of wavelength broad, the utilization ratio of all luminous energy is increased, even can directly utilize natural light if can adopt suitable processing method.
In addition, because pumping plant or other industrial waste gas gas flow are generally higher, in the time of staying that light catalytic purifying is indoor very limited (how below 5 seconds), and the speed of light-catalyzed reaction is relatively slow, and some pollutant also has little time to react with active particle.Therefore, need take suitable method, optionally increase the time of staying of contaminant molecule in photocatalytic region.Simultaneously in the photocatalyst district, also can produce small amount of ozone, how fully ozone and to reduce its loss also be one of key issue of photocatalysis waste gas purification technology.
The utility model content
This utility model provides a kind of photocatalysis technology that utilizes, with the eliminating malodours from gases device of the smell substance oxidation Decomposition in the waste gas.
The technical solution of the utility model is: comprise housing, the air inlet/outlet at housing two ends, the intravital gas passage of shell, be provided with filter screen in gas passage, be provided with the active carbon fiber photocatalyst layer behind the filter screen in air flue, be provided with ultraviolet source in the side of this layer.
Described active carbon fiber photocatalyst layer is made of frame, support bar and the NACF that is located at wherein.
Described active carbon fiber photocatalyst layer is 3～11 layers, and interlayer is established ultraviolet source.
Described air flue two ends are respectively equipped with gas guide board.
This utility model is based on photocatalysis technology principle and absorption-kinetics theory, and being provided with in air flue with the activated carbon fiber is the Filtration Adsorption layer of carrier of photocatalyst.Because activated carbon fiber has characteristics such as porous is good, specific surface area is big, can make catalyst even, stable be dispersed in its surface.To be loaded with the NACF of modified light catalyst, insert in the photocatalysis chamber, under the irradiation of common uv lamp, get final product work with certain form.In addition, activated carbon fiber material is except that being used as catalyst carrier, also have the good adsorption effect concurrently, can in time be played " temporarily " adsorption with failing in the waste gas by the material of catalytic decomposition, thereby optionally prolonged the time of staying of contaminant molecule, helped the abundant removal of pollutant in photocatalytic region.
The utlity model has the purification efficiency height, energy consumption is low, capacity usage ratio is high, facility compact, purification thoroughly reach characteristics such as good economy performance, be suitable for big flow, low concentration gas or foul gas and purify.
